5c1e9c39ef Cleanup ConstantFoldCompareInstruction: 
1. Make the arguments const like the other ConstantFold* functions.
2. Clean up evaluateFCmpRelation so it makes sense for floating point.
3. Implement the use of evaluateFCmpRelation to fold floating point CEs
4. Shorten a variable name so more things fit on one line.
5. Fix various comments.

66a349efb1 For PR1066: 
Fix this by ensuring that a bitcast is inserted to do sign switching. This
is only temporarily needed as the merging of signed and unsigned is next
on the SignlessTypes plate.

been replaced with ICmpInst and FCmpInst.

812cc9c807 Now that ConstantInt::isValueValidForType can handle signed and unsigned 
values regardless of the signedness of the constant's type, it is okay to
always make the AsmWriter.cpp print constant ints as signed values. The
AsmParser will automatically handle things like: uint -1 as a result.

2f7cae1f57 Fix a long-standing spiller bug: 
If a spillslot value is available in a register, and there is a noop copy that
targets that register, the spiller correctly decide not to invalidate the
spillslot register.

However, even though the noop copy does not clobbers the value. It does start a
new intersecting live range. That means the spillslot register is available for
use but should not be reused for a two-address instruction modref operand which
would clobber the new live range.

When we remove the noop copy, update the available information by clearing the
canClobber bit.

a82b285a69 Implement createIntegerCast and createFPCast factory methods for handling 
integer and floating point cast creation. createIntegerCast generates
ZExt/SExt, BitCast or Trunc. createFPCast generates FPExt, Bitcast, or
FPTrunc.
